Hi

I have solved above mission, but probably in another way that what tests are expecting. All asserts are ok, but I get this:

sys.stderr.write(strtraceback(e, *sys.excinfo())), File "/opt/project/runners/py3.py", line 191, in strtraceback, return strframes(ex, filename, gettracebackframes(filename, *args)),TypeError: gettracebackframes() missing 1 required positional argument: 'tb',

Any hints on what I am missing? I have solved it using classes and plain Python.
